The processing of vacuum casting prototype

 

We usually use CNC maching to processing prototype ,but the CNC tooling is hard , can only  process hard material.So if customer need to make rubber product ,we will not be able to use CNC machining .In that time ,we will use vacuum casting to process.vacuum casting is the best way to make rubber product in small quantity.So how vacuum casting to process a prototype?

1,programming.

2,make a mold.

3,Pour the liquid soft rubber material into the mold and take it out after cooling.

4,surface finish:

If those rubber product need to do color,there have two way to make color.one is painting after the product out of mold .Another is the color and the product out of mold together.This mean mix the color powder andrubber materials required by the customer into the mold, and take them out after cooling.

At this time, the product comes with its own color when it comes out of the mold. But the price will be more expensive than painting.

The surface of the vacuum casting product is smooth, and generally does not need manual processing. Which can save manual processing time.

If you have rubber products to make, please contact E-make. We are a rapid prototyping manufacturer in China, with over 10 years of experience in CNC,3D printing, vacuum casting and injection molding die-casting prototypes. We can quickly and cheaply produce high quality parts and prototype for you.

The difference between anodizing and painting in the surface finish of prototype processing

/in , , /by

Anodizing and painting are common surface finish processes when making prototype models. Although anodizing and painting both make the surface of the prototype color, there are still differences between them, which are mainly reflected in the following three aspects:
1.For different materials, painting can be applied to many materials for prototypes, such as metal, plastic and resin, and anodizing is a surface finish process that only aluminum alloy prototypes have.
2.The color persistence is different. Because the painting only painting a layer of paint on the surface of the prototype, it will fall off over time, and the anodizing is to soak the aluminum alloy prototype in the potion to form an oxide film on the surface.Because the alumina produced by anodizing is a stable substance, it is difficult to react with oxidation in the air, so the color of the surface is relatively stable and not easy to fall off.
3.The effect is different. The anodizing color has a metallic texture. If you use painting, you will not be able to adjust that effect anyway.

The four major importance of prototype model manufacturing

/in , /by

First, design optimization：Modern industrial design encompasses a wide range：For example, small items such as paper clips and pens, as well as large items such as airplanes and ships, all contain the shadow of modern industrial design, but the design of so many commodities is not the same.
Second, design evaluation：In the process of commodity design, evaluation is very important. compared with the 2D representation of the plane, the prototype model can make the details of the product clearer and the visual feeling of the product more intuitive.
What’s more,Function test: The making of prototype model can be used for some function test,and able to imitate the shape of the finished product, including functional shape, surface shape, etc.Using materials with a certain strength (such as ABS, PC, etc.), it is possible to produce functional prototype containing the internal layout,then in order to check whether the layout of goods is reasonable, wall thickness is in line with the requirements, moving parts are smooth and so on.
Finally,Reduce capital: The steady promotion of the design process is very necessary, so in the early stage of commodity design to timely find the shortcomings in the process of commodity design, timely correction, and then to prevent the subsequent problems, during which prototype manufacturing is an important part that can be used.The manufacture of prototype model is a useful method of company capital control.

The way of making large-scale prototype

/in , , /by

In the rapid prototyping industry, most of making the prototypes are small size of prototype,then the small size of the prototype will does not exceed the machine’s processing stroke, so the processing is relatively easy.But sometimes, the rapid prototyping manufacturer will also encounter some customer requirements to produce larger size prototype, especially the length of the prototype more than 1000mm, but that will more than CNC processing travel of a lot of rapid prototyping manufacturer, and the Processing will be more difficult.In view of this situation what processing method should be used more suitable for making large-scale prototype ?

When making large-size prototype, it is mainly because of its large volume. Therefore, if the machining stroke of CNC is relatively small, we need to disassemble the prototype for production, and then glue each part together.But in here we need to pay more attention to the choice of material, this way of producing the prototypes can not affect the strength and appearance of the prototype.3d printing is an expensive way to produce prototypes. The main reason is that the materials in this way are more expensive. Large-size prototype naturally require more materials.And some 3d printers may not be able to print such a large prototype, so the more reasonable processing way is CNC machining.

The E-make company is capable of CNC machining with accuracy up to ±0.01mm.And E-make company has been providing high quality rapid prototype manufacturing services for major enterprises.If you need any help,please feel free to contact me.

 

The difference between injection moulding and rapid prototype

/in , , /by

The prototype is usually processed with plastic or metal on a CNC machine or 3D printed or vacuum casting, making several samples or small batch production.The use of the mold refers to the processing of the mold first, and then using the mold to injection mold the batch production of products. Generally, a prototype is provided to the customer for confirmation, and after the confirmation, the mold is used for mass production.

And The prototype is the sample of the product. When your design drawing comes out, the product just designed cannot be perfect in general, and may not even be able to be used. Once there is any defect in direct production, all the products will be wasted, and it will greatly waste human and material resources and time.The production cycle of prototype is short, the loss of manpower and material resources is less, can quickly find out the shortcomings of product design and then improve it, for the product design to provide sufficient basis for mass production.

The mold is the metal mold of each plastic and metal piece after the confirmation of the prototype, which can produce the parts with certain shape and size precision requirements.It is steel model commonly, to machine tool, cutlery requirement is a lot higher than processing prototype, and processing cost is also a lot higher.The commodity such as the shell of the TV set, telephone, plastic bucket that we live commonly, it is to heat plastic to pour into mould to cool molding production.

Which material is good for making transparent prototypes?

/in /by

Take ordinary two kinds of transparent materials, PC and acrylic as an example.From the point of polishing, the time spent on the PC prototype is relatively long, because its material properties are relatively hard, and some small places cannot be polished with force.Even where it is convenient for people to polish, the time it takes for the acrylic prototype also is long.

On the contrary, because the material performance of the acrylic material is relatively soft, then it is convenient for people to use the acrylic material as the transparent prototype.

About the transparent prototypes,The E-make team has more than 30 years of combined experience in prototype machining, vacuum casting service ,CNC manufacturing, and has a high-level technological group of 25 peoples. E-make company looking forward to having a chance to serve you! If there have anything we can do for you,please feel free to contact us!

CNC Machining Prototype

CNC rapid prototyping,a processing with fast producing speed,using raw material to manufacturing prototype by CNC machine.The cnc machined parts with nice surface finish,especially after painting,silk-printing and PVD coating, the surface’s effect is very closed to the moulding machining parts.
CNC manufacturing can use ABS,POM,PC,PA,metal and other material to machining prototype for satisfying different customer’s request.However,the prototype will have very great strength and toughness if the machined material is with high quality and high density.

The Cost Of CNC Precision Machining

1.The material cost is lower if using pure ABS,PP and the other pure material.
2.CNC machining process need to program the procedure and split the parts sometimes,but one cnc machining equipment needs to be operated by 3 or 4 workers,that’s why cnc machining takes more labor cost.Therefore,the cost of cnc machining is up to the complexity and the expending of material.More complex parts needs more workload for splitting and programming,which means will takes more working time and machining cost.

The Advantage Of CNC Machining
1.Using engineering plastics has cheaper price and more selection of materials.
2.The cnc machining equipment with more stable performance,is easier to operate.
3.CNC machining processing is more suitable for producing the parts with large size and simple structure.

The Material That CNC Machining usually use is ABS 、PC、POM 、PP 、PMMA、Nylon、bakelite、aluminum alloy、Zinc alloy、mild steel、copper、stain steel，etc.,
